Description
The current study investigated whether intermittent restraint stress (IRS) would impair fear extinction learning and lead to increased anxiety and depressive- like behaviors and then be attenuated when IRS ends and a post- stress rest period ensues for 6 weeks. Young adult, male Sprague Dawley rats underwent restraint stress using wire mesh (6hr/daily) for five days with two days off before restraint resumed for three weeks for a total of 23 restraint days. The groups consisted of control (CON) with no restraint other than food and water restriction yoked to the restrained groups, stress immediate (STR-IMM), which were restrained then fear conditioned soon after the end of the IRS paradigm, and stress given a rest for 6 weeks before fear conditioning commenced (STR-R6). Rats were fear conditioned by pairing a 20 second tone with a footshock, then given extinction training for two days (15 tone only on each day). On the first day of extinction, all groups discriminated well on the first trial, but then as trials progressed, STR-R6 discriminated between tone and context less than did CON. On the second day of extinction, STR- IMM froze more to context in the earlier trials than compared to STR-R6 and CON. As trials progressed STR-IMM and STR-R6 froze more to context than compared to CON. Together, CON discriminated between tone and context better than did STR-IMM and STR-R6. Sucrose preference, novelty suppressed feeding, and elevated plus maze was performed after fear extinction was completed. No statistical differences were observed among groups for sucrose preference or novelty suppressed feeding. For the elevated plus maze, STR-IMM entered the open arms and the sum of both open and closed arms fewer than did STR- R6 and CON. We interpret the findings to suggest that the stress groups displayed increased hypervigilance and anxiety with STR-R6 exhibiting a unique phenotype than that of STR-IMM and CON.

Description
Monoamine neurotransmitters (e.g., serotonin, norepinephrine, and dopamine) are powerful modulators of mood and cognitive function in health and disease. We have been investigating the modulation of monoamine clearance in select brain regions via organic cation transporters (OCTs), a family of nonselective monoamine transporters. OCTs are thought to complement the actions of selective monoamine transporters in the brain by helping to clear monoamines from the extracellular space; thus, assisting to terminate the monoamine signal. Of particular interest, stress hormones (corticosterone; CORT) inhibit OCT3-mediated transport of monoamine, to putatively lead to prolonged monoamine signaling. It has been demonstrated that stress levels of CORT block OCT3 transport in the rat hypothalamus, an effect that likely underlies the rapid, stress-induced increase in local monoamines. We examined the effect of chronic variable stress (CVS) on the development of mood disorders and OCT3 expression in limbic and hypothalamic regions of the rat brain. Animals subjected to CVS (14-days with random stressor exposure two times/day) showed reduced body weight gain, indicating that CVS was perceived as stressful. However, behavioral tests of anxiety and depressive-like behaviors in rats showed no group differences. Although there were no behavioral effects of stress, molecular analysis revealed that there were stress-related changes in OCT3 protein expression. In situ hybridization data confirmed that OCT3 mRNA is expressed in the hippocampus, amygdala, and hypothalamus. Analysis of Western blot data by two-way ANOVA revealed a significant treatment effect on OCT3 protein levels, with a significant decrease in OCT3 protein in the amygdala and hippocampus in CVS rats, compared to controls. These data suggest an important role for CORT sensitive OCT3 in the reduction of monoamine clearance during stress.

Description
This Barrett, the Honors College senior thesis connects the experiences of cosplay with public speaking confidence. “Cosplay, abbreviated from the word ‘costume play,’ is a performance art in which the participant masquerades as a character from a selected film, television, video game, or comic book” (Gn, 2011, p. 583). The ability to “cosplay” in front of other relies on performing in front of an audience much like public speaking. When students speak with confidence, students will know their ideas are being expressed with conviction and assurance. Having the ability to speak professionally and publicly, is a highly valued skill in the workforce and key to success in all types of employment. Communication skills are frequently a top factor in determining whether a college student will obtain employment (Beebe & Beebe, 2006, p. 275-276). Despite their different definitions, there are multiple connections between cosplay and public speaking. This thesis explores the connection between peer support and belief in one’s self in both cosplay and public speaking. Now those who have direct support become self-reliant and confident as a result of these connections. This projects highlights Goffman’s identity theory, the Pygmalion effect, theories of fashion and identity, role-play, narrative paradigm, dramatism, and non-verbal communication, and explores how cosplay can contribute to the formation of one’s public speaking persona. The issue of anxiety is also included in the conversation as it is central to both cosplay and public speaking. Ultimately, this thesis explores the questions: Can cosplay help students become empowered public speakers?

Description
The goal of our study is to identify socio-economic risk factors for depressive disorder and poor mental health by statistically analyzing survey data from the CDC. The identification of risk groups in a particular demographic could aid in the development of targeted interventions to improve overall quality of mental health in the United States. In our analysis, we studied the influences and correlations of socioeconomic factors that regulate the risk of developing Depressive Disorders and overall poor mental health. Using the statistical software STATA, we ran a regression model of selected independent socio-economic variables with the dependent mental health variables. The independent variables of the statistical model include Income, Race, State, Age, Marital Status, Sex, Education, BMI, Smoker Status, and Alcohol Consumption. Once the regression coefficients were found, we illustrated the data in graphs and heat maps to qualitatively provide visuals of the prevalence of depression in the U.S. demography. Our study indicates that the low-income and under-educated populations who are everyday smokers, obese, and/or are in divorced or separated relationships should be of main concern. A suggestion for mental health organizations would be to support counseling and therapeutic efforts as secondary care for those in smoking cessation programs, weight management programs, marriage counseling, or divorce assistance group. General improvement in alleviating poverty and increasing education could additionally show progress in counter-acting the prevalence of depressive disorder and also improve overall mental health. The identification of these target groups and socio-economic risk factors are critical in developing future preventative measures.

Description
In 2012, President Obama presented an executive order, Deferred Action for Childhood Arrivals (DACA), which primarily defers the deportation of unauthorized immigrants who are under the age of 31 and who arrived to the US before the age 16, among other things. This study examines the impact DACA has had on the identity formation, interfamilial relationships, and future plans of 15 Mexican-origin adults (18-27 years old, 47% female) who were approved for DACA in Arizona. Participants were recruited using flyers and the snowball sampling method. Interviews were conducted using a semi-structured interview guide by a bilingual, culturally competent interviewer. The interviews were recorded and then a transcript-based pragmatic, thematic analysis of the interviews was conducted. Findings show that participants who arrive to the U.S. at a younger age (under 5) identify as American, while those who arrive at an older age (over 8) do not feel like they can identify as an American because they spent more time in Mexico and are more attached to their home culture. Physical characteristics also played a factor in whether or not participants felt like they could identify as American. Participants describe their financial responsibility in their families increasing since receiving DACA. They also describe how they are now seen as role models to other undocumented youth in their families. Despite the uncertain future of DACA, these participants continued to have ambitious goals such as becoming lawyers and working at robotics companies. Future studies should include larger sample sizes and formally test theories of identity.

Description
This study examines the effectiveness of two modes of exercise on depression in adolescents with Down syndrome (DS). Thirty nine participants were randomly divided into a voluntary cycling group (VC) (i.e., self-selected cadence), an assisted cycling group (AC) (i.e., at least 30% faster than self-selected cadence accomplished by a motor), or a no exercise group (NC). In each cycling intervention the participant completed 30 minute cycling sessions, three times per week for a total of eight weeks. The Children's Depression Inventory II was administered prior to cycling (i.e., pretest) and after the eight week intervention (i.e., posttest). Although the data did not reach conventional levels of statistical significance, the results of the study demonstrated partial support for our hypothesis that adolescents with DS showed improvements in depression as measured by the Children's Depression Inventory II following assisted cycling, but not following eight weeks of voluntary cycling. In other words, eight weeks of moderate AC exercise demonstrated a trend for improved depression in adolescents with DS.

Across the world, nations manage their borders in various ways. Brazil and Uruguay share a non-militarized dry border, which creates a range of unique challenges and assets for that region. Through historical, linguistic, and cultural context as well as ethnography-inspired mixed method research, this paper demonstrates that the border region serves as an area of cultural blending. While elements of national affiliation are still present, at times, semiotic and linguistic elements are neither Brazilian nor Uruguayan, but have taken on their own identity.

Description
The purpose of this paper will be to show that the 'merge' model of mental files is to be preferred to the 'link' model of mental files because some of the problems that arise for the 'merge' model also arise for the 'link' model, and because the problems for the 'merge' model can be argued against via counterexamples or explained away. This will be shown by giving a detailed description of what both the link model and the merge model of mental files entail. The flaws of the mental file merge model will be presented, followed by the advantages of the link model, ending with several arguments as to why the merge model is better suited to explain our intuitions about identity than the link model.

Body Integrity Identity Disorder Screenplay Abstract
The Body Integrity Identity Disorder Screenplay, tentatively entitled Detach, is a full-‐length feature film script. Based on a fascinating mental disorder (generally referred to as the acronym BIID) where an individual does not associate a limb with the rest of their body, the script follows a sufferer and a reporter attempting to write a story on his struggle.
As my creative sensibilities and skills have developed over the span of my undergraduate career, the most ambitious undertaking imaginable for myself at this moment is the completion of a feature script. This project was a significant test of my storytelling skills and ability to format an unusual tale into a conceivable film.
I am proud of the end result and believe that the final version of my screenplay is an accurate representation of my taste as a filmmaker. I hope to actualize this project one day and help facilitate a transformation of the script into a feature film.
